Table 4 Adopted phase state labels for single phase regions, across all mapped phase diagrams.

Dataset Label	Lit. Label	Description
E	Ice	Ice
H1	H₁	Hexagonal phase
H2	H₂	Inverse hexagonal phase
I1	I₁	Cubic micellar phase
I2	I₂	Inverse cubic micellar phase
L1	L₁	Isotropic micellar solution
L2	L₂	Isotropic reverse micellar solution
L3	L₃	Sponge phase
La	L_α	Lamellar phase
La1	Soap Boilers Neat Soap	Lamellar phase
La2	Superneat Soap	Lamellar phase
Lb	L_β	Gel phase
M1	M_α	2D Monoclinic phase
N1	N₁	Nematic liquid of rod- or worm-like micelles
Pb	P_β’	Hydrated bilayer-based rippled phase
R1	R_α	Rhombohedral phase
S	Neat Soap	Non-crystalline solid
Sa	S_α	Non-crystalline solid
Sb	S_β	Non-crystalline solid
T1	T_α	Tetragonal phase
V1	V₁	Bicontinuous cubic phase
V2	V₂	Inverse bicontinuous phase
V2i	V2_i	Inverse bicontinuous phase with space group Pn3m
V2m	V2_m	Inverse bicontinuous phase with space group Ia3d
V2p	V2_p	Inverse bicontinuous phase with space group Im3m
W	W	Water phase or sub-micellar solution
X	X	Generic crystalline (solid) surfactant phase
X1, X2	X₁, X₂	Solid surfactant phases (differing by hydration state)
U		Unmeasured / unknown / unclear region or phase state

Presented are both the phase state label used in the data set and the corresponding typical literature label. To allow for future expansion we include an I2 cubic micellar and V2m phase although it is not needed in the present dataset. The X1 and X2 labels distinguish solid surfactant phases with different hydration states and are needed in phase diagrams where there is X1+X2 coexistence.
